HORACE G. SWOPE, OF LIBERTY, INDIANA.

SEEDING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 245,027, dated August 2, 1881, Application filed May 9, 1881. (ModeL) To all whom it may concern Be it known that I, HORACE G. SwoPE, of Liberty, in the'county of Union and State of Indiana, have invented a new and useful Improvement in Seeding-Machines, of which the following is a specification.

My invention relates to an attachment and movement of the bars for shifting the hoes of a-seeding-machine by which thehoes can be thrown from a single to a double rank, or vice versa, as desired and the novelty consists in the peculiar formation of the mechanism by which the bars are fastened to the side frame of the machine and the movement back and forth obtained.

In the accompanying drawings, Figure 1 is a plan view of a seeding -machine with the drag-bars properly attached to the'shiftingbars. Fig. 2 isa section of one end of the shifting-bars, showingthe bars side by side and the construction of the shifting mechanism. Fig. 3 is a similar section, only showing the shifting-bars apart. Fig. 4 is a vertical section, looking endwise through the side frame and the hanging bracket, showing the attachment of the latter to the frame. Fig. 5 is a similar view, showing the pintle ofthe haugiu'gbracket engaged in slot of the bell-crank connected with the front shifting-bar. v

A, B, O, and D compose the frame of the machine. E is the hopper in which the seed is placed. F and G are the front and rear shifting-bars. H H H H are the drag-bars.

I is the handle used for shifting them back and forth. J is the hanging bracket, having its upper portion cast at right angles, in order that it may serve as a means of attachment and support to the shifting-bar Gr.

A pin, 1), extends out from the side pieces, B and O, which serves as a fulcrum for the bracket, and around which the latter moves. K is a bell-crank having slots 8 and .9. Into these slots pintles p and p fit, the pintlep .being part of bracket J and pintle p a part of a right-angular plate, L, attached to the shifting-bar F. This bell-crank is so fastened to the side pieces, B and O, by a screw or bolt that it is enabled to be turned back and forth as the bars are shifted.

One-half of the drag bars are attached to the shifting-bar G and one-half to the bar F, and these drag-bars are of such length that when the bars are close together, as in Figs. 1 and 2, the hoes will be in a line or single rank to shiftthem to double rank. When shifting the hoes from a double to a single rank the lever I is pulled back, bringing with it the bar G. This elevates the lower part of the bracket J, and the pintlep working in the slots throws the bell-crank forward. The

slot 8 moves the pintle p and carries with it .the right-angular piece L and bar F, and thus the operation is completed. By the reverse movement of the lever I the hoes are again brought in line in single rank.

A metal piece, such as P, is fastened to the side frames, B and G, in order to facilitate the workingof the mechanism and save the framework from damage by friction. This piece has a slotted guide, S, in which the bar-F slides back and forth.

' I claim 1. In the shifting mechanism of a seedingmachine the bracket J, pintle p, bell-crank K, having slots 8 and s, in which work pintles p and 12, substantially as and for the purpose specified.

2. In combination with a seeding-machine, the shifting'bars having hanging bracket J, slotted bell-crank K, pintles p. and 19 working therein, all pivoted and working substantially as shown, and for the purpose specified.

3. In a seeding device, the shifting-bars F and G, provided withpintles p andp,operating in the slots of the bell-crank K, as and for the purpose described.

4:. In a seeding-machine, the combination of two bars for shifting the hoes, one of which slides horizontally and the other of which swings through the arc of a circle.
